Language transfer refers to the application of previous language knowledge to the target language learning. Using questionnaires, this paper investigates the lexical transferring behaviors of 230 Dongxiang-Chinese bilingual and monolingual students who are in the early stage of learning English vocabulary. The results display that Chinese predominates the transference, while bilinguals’ Dongxiang Language is described as a barrier during the process of English learning. To show the individual-level differences, several learner-based factors: age, linguistic background, social background, cognitive level, emotion, and learning attitude are also confirmed, which appear to promote or inhibit this transferring behavior. The experiment data suggest that there are two different types of the factors mentioned above, which depend on whether they are affected by context-based factors---learner-based factors and learner-context-based factors. The paper also concludes with suggestions to teachers and policymakers in Dongxiang area for the modification of current teaching methods based on the quantitative analysis of surveys.
